Summary: This draft is almost ready for publication, but has minor issues/open
points that should be fixed before publication.

Major issues: N/A

Minor issues / questions:

* Section 3: At the end of season 3, you indicate that this new flag has no
meaning in PCRpt and PCInitiate messages. RFC8231 defines that the SRP Object
MAY be carried in PCErr as well, shouldn't there be such requirements (MUST be
set to 0, MUST be ignored on reception) for PCErr?

* In the following text (Section 4): "The PCE SHOULD NOT
   send control request for LSP which is already delegated to the PCE,
   i.e. if the D Flag is set in the PCUpd message, then C Flag SHOULD
   NOT be set." Why is there a SHOULD NOT instead of MUST NOT? In which
   situation could it be acceptable or useful to request control for a
   delegated LSP?

Nits/editorial comments:

* Terminology should also include a sentence about the reader being familiar
with at least RFC8231.

* Terminology could also include what SRP stand for.

* Section 3. When introducing SRP, it would have been helpful to the reader to
reference section 7.2 of RFC8231.

* Section 3. "PCE sets the C Flag to 1 to indicate that, it wishes" -- remove
","

* Section 3. "MUST be ignored on receipt" -- "MUST be ignored on reception"

* Section 4. When introducing the D flag, it would have been helpful to the
reader to reference section 7.3 of RFC8231.

* Section 4. "Note that, the PCUpd message with C Flag set is received" --
"Note that, if the PCUpd message with C Flag set is received"
